近日，首钢京唐钢铁联合有限责任公司钢轧部MCCR（多模式全连续铸轧）生产线有序运转。    STOCKHOLM -- A Swedish court on Wednesday fined climate activist Greta Thunberg once again for disobeying police during an environmental protest in July in southern Sweden.The Malmo District Court ordered her to pay a 2,250 kroner ($206) fine.Thunberg, who already had been fined for a similar offense, took part in a July 24 environmental protest at an oil terminal in Malmo, where activists temporarily blocked access to the facility by sitting down and were removed by police.On Sept. 15, she was charged with disobedience to law enforcement for refusing to obey police asking her to leave the scene. She then was dragged away by two uniformed officers. Thunberg, 20, has admitted to the facts but denied guilt, saying the fight against the fossil fuel industry was a form of self-defense due to the existential and global threat of the climate crisis.”We have the science on our side and we have morality on our side. Nothing in the world can change that and so it is. I am ready to act based on the conditions that exist and whether it leads to more sentences,” she said after the verdict. On June 24, the same court fined her 2,500 kronor (about $230) for refusing to obey police orders when taking part in a similar demonstration the previous month where she and others blocked access to the same oil terminal days earlier and were removed by police.On Thursday, the Swede is due to travel to neighboring Norway to take part in a protest with activists, including Indigenous Sami. They're protesting a wind farm of 151 turbines and want it removed because they say it endangers the reindeer herders’ way of life. The activists say a transition to green energy shouldn’t come at the expense of the rights of Indigenous people.Two years ago, Norway’s Supreme Court ruled that the construction of the turbines had violated the rights of the Sami, who have used the land for reindeer for centuries. The Norwegian government has no plans to remove the wind farm.Thunberg inspired a global youth movement demanding stronger efforts to fight climate change after staging weekly protests outside the Swedish Parliament starting in 2018.。这条短流程产线与传统热轧生产线相比，生产时间缩短3个小时，实现综合节能30%以上。

二 | 日报记者 赵 杰摄“0.75毫米超薄钢卷市场反馈好，又来新订单了。”近日，在位于唐山市曹妃甸区的首钢京唐钢铁联合有限责任公司，接到公司系统派发的订单任务，钢轧部MCCR生产线首席作业长马硕立即组织工人加紧赶制产品。

三 | 在马硕面前，是一条全长288米的MCCR（多模式全连续铸轧）生产线。只需25分钟，红彤彤的滚烫钢水轧制成0.75毫米的超薄钢卷，薄如蝉翼，状如红绸。“超薄钢卷中，我们最薄能生产0.7毫米。0.75和0.8毫米两种规格销量大，很多出口到非洲、中东、南美地区。

四 | ”马硕说。这些超薄钢卷市场走俏，除了契合产品轻量化需求，绿色属性也是其一大优势，大大提高了首钢京唐在国际市场上的绿色竞争力。“这是全球首条集单坯、半无头、全无头三种轧制模式于一体的短流程产线。与传统热轧生产线相比，生产时间缩短3个小时，实现综合节能30%以上。”首钢京唐炼钢工艺首席工程师闫占辉说。传统热轧需要先将钢水浇铸板坯，再转运到热轧机组轧制成钢卷。

五 | 而MCCR生产线实现高温钢水铸坯、轧制一体化成卷，省去铸坯冷却、储存环节，充分利用高温铸坯的余热效能，显著降低了每吨钢材生产能耗。

六 | 目前，MCCR生产线产品包括热轧板卷、热轧酸洗板、热基镀锌板等，广泛应用于汽车、光伏支架、集装箱等多个制造领域。随着“双碳”目标推进，首钢京唐启动实施环保绩效创A，探索特色节能降碳路线。MCCR生产线是其深度降碳的一项重要创新。

七 | 其实，MCCR生产线建成前，首钢京唐已有两条传统热轧产线稳定运行。为何要建一条轧制工艺完全不同的新产线呢？据了解，一方面，传统热轧有轧制极限，钢卷厚度1.2毫米就接近极限了，他们想打破工艺极限。另一方面，传统热轧耗能较高，他们想试验一条流程更短、降碳效果明显的全新产线。然而，原始创新是从0到1的突破，无捷径可走。从MCCR生产线热试到全面达产，他们整整用了两年时间。

八 | 轧制一卷钢，需要生产线300多万个零部件协同作业，不能出现任何细微误差，难度可想而知。另外，钢卷轧得越薄，轧速越快，轧到0.75毫米时钢坯前进速度达到每秒12米，对作业精度带来极大挑战。

九 | 没有经验可循，只能自己摸索。

十 | 面对板坯控制难度大、薄规格钢卷头部容易折叠等一项项难题，科研团队夜以继日地钻研，对感应加热线圈结构进行改造，对精轧薄规格最优负荷分配等创新设计。一系列措施落地，这才实现项目达产达效。实现深度降碳，仅靠绿色轧制工艺还不够。近些年，公司瞄准MCCR生产线上游炼铁、炼钢工序持续攻关，提升含绿量，实现源头降碳。

十一 | 首钢京唐研制出70%高比例球团矿冶炼工艺并实现稳定运行，标志着该技术在高炉炼铁上的应用取得重大突破。“跟传统烧结工序相比，高比例球团矿冶炼技术降耗明显，吨铁可降低碳排放10%以上。”闫占辉说，公司建设了3台球团矿带式焙烧机，配套3座高炉使用。近年来，从50%到55%再到70%，高炉冶炼原料球团矿的占比越来越高。在炼钢环节，首钢京唐联合首钢集团技术研究院成立专项攻关组，探索推进长流程高废钢比冶炼的工艺路径。废钢是可供转炉炼钢使用的原料。研究显示，每使用1吨废钢，可以节约0.4吨焦炭或1吨左右的原煤，比用铁水节能60%、节水40%。然而，过多的废钢会对钢水温度、钢水成分造成不良影响。闫占辉回忆，长流程高废钢比冶炼工艺的难点在于热量平衡。针对这一难题，他们创新实施“三步补热”工艺，即在吹炼前期、中期、后期动态调整补热原料，解决了热量失衡痛点问题。目前，该公司实现转炉单工序50%废钢比批量稳定生产，具备转炉单工序55%废钢比冶炼能力。多年来，首钢京唐依托多项自主核心降碳工艺、固废循环利用技术，构建全流程能效管控体系，去年成功入选首批重点行业环保绩效创A领跑企业。创A创出绿色生产力。首钢京唐研制的高废钢比低碳汽车板、全规格镀锡板、锌铝镁高耐蚀镀层钢等产品已通过第三方EPD（环境产品声明）的审核认证，实现产品大类EPD全覆盖。以环保绩效创A带动企业转型，首钢京唐的绿色发展之路越走越宽广。（日报记者 贡宪云 王育民）。
